Title: Improvements in and connected with signalling apparatus for use in mines
IPC: B66B19/06
Filed: 1920-04-10
Abstract: 169,473. Ross, J., and Ross, A. April 10, 1920. Mine and colliery signals. -- In signalling apparatus for use in mines, a spindle carries a ratchet - wheel D keyed to the spindle and a second ratchetwheel loosely mounted thereon. A pointer J moving over a dial is fixed to the spindle C, and a disc H, is attached to the looselymounted wheel. The disc H bears two sets of numerals, one set comprising repeated indications " 3 " or " men " and the other set " level " indications, and one indication of each set is exhibited in the apertures A1, A2. The signal rope b, Fig. 7, is attached to levers T, e, and the wheel D is turned by means of a pawl R, Fig. 2, on a pawl rod R operated through levers Q, S by the lever T. The second wheel is turned by the wheel D by means of driving-pins. The wheel D is prevented from returning to zero by the prong Y, of a catch Y which is pivoted to the frame and the lower end of which is weighted, whilst the second wheel is retained by a pawl a1, on a rod a, which is also weighted to keep the pawl a1 in mesh with the wheel. At the commencement of operations a lever k, pivoted at k1, keeps the pawls a1, R, out of mesh with the ratchet wheels. On the signal rope b being pulled, the hammer f, Fig. 7, is raised, the lever k falls, and the pawlrod R, Fig. 2, is lifted. To this rod is attached a plate q, which raises the flange V of the oil-pump U acting as a dash-pot. When the signal-rope is released, the hammer f strikes the bell g, and the pawl-rod R descends, the pawl R, moving the wheel D through one step. The second wheel is carried round bv the wheel D. Between the strokes of a signal, the wheel D is prevented from returning to zero bv the prong Y, of the catch Y, but when a pause occurs the flange V of the oilpump carries down the prong Y2 of the catch Y and releases the prong Y1 from the wheel D, allowing it to return to zero. The second wheel is held by the pawl a,. The lever T rests on an arrangement of levers on which the lever k also rests, and on the first stroke of a signal these levers are pulled into a position in which a pin on the cross-head of the engine can strike one of them when the engine is moved to comply with the order, so that they are moved back to the original position, raising again the lever k to knock the pawls R1, a, from engagement withboth ratchet-wheels and allowing the whole apparatus to return to zero position.

Title: Improvements relating to magnetic matrix stores
Inventor: HOUNSFIELD GODFREY NEWBOLD
IPC: G11C7/02
Filed: 1964-03-11
Abstract: 1,103,871. Magnetic storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. 5 March, 1965 [11 March, 1964], No. 10197/64. Heading H3B. In a magnetic store comprising a stack of sub-matrices, each sub-matrix is formed by bringing together in face-to-face relationship two flat members having magnetic properties and belonging to different groups of members, each member having in its surface a parallel set of conductors which is continuous with at least one other member of the group, the parallel conductors of one group of members being orthogonal with respect to the parallel conductors of the other group. Each flat member may consist of a sheet 15, 16, Fig. 2, of glass or metal having parallel conductor grooves accommodating strips of magnetic material 17-20, the magnetic material preferably being deposited in a magnetic field which establishes a diagonal easy axis. Alternatively the flat members may incorporate magnetic material such as a ferrite. The parallel conductors may be separate insulated copper conductors 21-26 or the conductors may be in the form of printed winding. Flexible mechanical support is provided where the conductors extend between one sub-matrix and another, Fig. 5 (not shown). The matrix store is formed by establishing a wired matrix of sub-matrices, Fig. 3a, and then progressively folding first along lines 28, 29, 30, in that order, for the Y co-ordinate, and then folding in similar manner for the X co-ordinate. A method of mounting the set of conductors on a series of spaced flat members using a removable rotatable mandril 32 and a wire feed assembly 38, Fig. 4, is described, the conductors being secured by adhesive. Details of adapting such sub-matrices to the magnetic store circuit shown in Fig. 1 are described, Figs. 6a and 6b (not shown). The magnetic store 5 comprises sub-matrices such as 7 having row conductors 2 connected to row drive selectors 6, 6<SP>1</SP> and column read/write conductors 4 connected to a group column selector 13. A column conductor in a selected group is energized for writing through a respective transistor 14, while a readout signal is detected by a read amplifier 12. Two-thirds switching currents are used in the rows and columns and a selected positive or negative bias of one third switching current is applied over a transistor 9 or 8 to a bias conductor 3 in respective sub-matrices. For reading, a positive bias current is applied to the selected sub-matrix and a negative bias to the other sub-matrices. A read current which augments the positive bias is then applied to a selected row conductor. For writing, all the submatrices are positively biased and a write current of opposite polarity to the read current is passed through a selected row. Simultaneously those transistors 14 which correspond to the " 1 " bits to be written are caused to conduct so that a positive write current from the column selector passes through the selected column.

Abstract: 799,003. Inductors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 4, 1956 [April 7, 1955], No. 10323/56. Class 38 (2). [Also in Group XXXVIII] In a controllable inductance A.C. windings 5, 6, 7, 8 are wound on a first closed magnetic core 1 which itself forms part of a second magnetic core whose flux is the controlling flux for the inductance, and the active parts 23 of the first core are each divided into two limbs 9, 10, 11, 12 which are saturated by alternate opposing unidirectional fluxes. The hysteresis curve for the portions of 2 and 3 is therefore as shown in Fig. 3 so that less area is traversed per cycle with consequential less hysteresis loss. The unidirectional saturating fluxes may be produced by D.C. windings 13-16 as shown or by permanent magnets (Figs. 6 and 7, not shown). As shown in Fig. 1, the arrangement forms an inductance with the controlling flux produced by a coil 17. In a modification, Fig. 5, the arrangement may be a magnetic play-back head, the controlling flux being produced in an air gap 22 and a pick-up winding 23 being provided. The A.C. windings and the windings producing the unidirectional fluxes may be conductors 24-28 perpendicular to the plane of the first core 1.

Title: Improvements in or relating to the production of inlay effects on embossed fabrics
IPC: D06Q1/08
Filed: 1954-04-08
Abstract: Embossing processes.-A process of producing a durable pattern effect in which the depressed parts of an embossed fabric are coloured includes the steps of applying to the relief surfaces of the heated engraved calender roller a paste containing the colour pigment, a heat-hardening alkyd resin and an oil or an oil-modified heat-hardening alkyd resin, simultaneously embossing the fabric and transferring the paste to the depressions in the fabric and heating the embossed fabric to a temperature and for a time sufficient to harden the resin.  The paste is applied to the calender roller by another roller, e.g. of rubber.  Where an oil-modified alkyd resin is used there may be an additional oil unless it is of the long oil type.  In this latter case the only oil constituent is that present in the modified alkyd resin.  The alkyd resin may constitute from 5 to 95 per cent by weight of the paste.  The oil may constitute from about 2 to 60 per cent by weight of the paste.  The paste may also contain a solvent soluble resin of the thermosetting type which may constitute from 0.5 to 15 per cent by weight.  The oil in the paste may be of the oxidizing or non-oxidizing type and a catalyst may be added which catalyses oxidation.  A high boiling-point solvent for alkyd resins may be incorporated into the paste.  Before calendering the fabric may be impregnated with a solution of a thermosetting resin and calendered with moisture present.  Several examples are given. In one a yellow dyed cellulosic fabric is impregnated with a resin solution consisting of a melamine resin, a cationic softener, a polyvinyl alcohol and a catalyst, partially dried and embossed, a paste being applied to the engraved steel roll.  The paste consists of a modified soya short oil alkyd resin, metallic driers, a solvent-soluble methylol melamine resin, methylhydroxy-propanolamine hydrochloride and pigment paste.  The pigment paste is composed of green dye, dehydrated castor oil and a modified soya long oil alkyd resin.  After embossing and printing in this manner the fabric is aired in a conventional ager for 2-3 minutes at about 300 DEG  F., then washed and dried.  A yellow embossed fabric with depressed portions in green is obtained.
